CLAY REDUCER AND PULVERIZER.

SPECIFICATION forming part of Letters Patent No. 351,613, dated ()ctcber26, 1886. Application filed May 25, 1886. Serial No. 203,212. No model.)

To all whom; it may concern:

Be it known that I, J AMES 0. ANDERSON, a citizen of the United States,residing at Highland Park, in the county of Lake, State of 5 Illinois,have invented certain new and useful Improvements in Clay Reducers orPulverizers, of which the following is a specification, reference beinghad therein to the accompanying drawings.

r My invention relates to improvements in clay reducers or pnlverizers.

The object of my invention is to reduce clay or clay-shale to a finelydivided or powdered condition for the manufacture of bricks, tiles,

1 850., under the dry-clay processes as patented and practicedby me.

Referring to the drawings, Figurel is a top or plan view of my improveddisintegrator or reducer. Fig. 2 is avertical longitudinal sec- 2otional view on the line :0 x of Fig. 1. "Fig. 3

is a sectional view on the line m w of Fig. 2. Fig. 4is a side view ofthe screen-shell with the casing removed. Fig. 5 is asectional view of aportion of a V-shaped screen shell. Fig.

2 6 is a sectional edge View of the screen with the supportingribs.

A indicates the base of the machine, on which the two shafts B and G aremounted in suitable supports, D, said shafts being pro- 0 vided withpulley-wheels E, adapted to be driven at a high rate of speed inopposite directions, as indicated by the arrows in Fig. 2, for a purposewhich will more fully appear hereinafter. The inner end of the shaft Bis 3 5 provided with a disk, F, rigidly secured there to and adapted torotate therewith, the outer edge of said disk being provided with a rowof arms or heaters, G, placed close together,

' which project toward the face of the disk H.

40 The central portion of thedisk H is provided with a hub or chamber,K,which projects over to the disk F, the walls of the hub or chamber Kbeing provided with any desired number of perforations L, through whichthe clay is fed 5 in between the disks at or near the center through thespout M, said spout being prO- vided with a suitable feed-hopper, N.

O are a series of perforated steel screenplates secured to the peripheryof the disk H,

5 0 said plates being provided with flanges P, by

means of which they can be readily secured together. These screen-platesare made wide,

so as to project over the disk F, asshown in Figs. 2 and 5, so as toprovide a greater screen surface, and the screen-plates may presentplain fiat surfaces, as shown in Figs. 2, 3, 4, and 6; or they may bemade concave or V- shaped, as shown in Fig. 5, in order that a greaterscreening-surface may be presented to the clay, and the clay will beprevented from being forced out the side by centrifugal force,

as would be the case if the screen were only as wide as the two disks.

The bed-plate A is provided with a central opening, R, underneath thedisks, through which the pulverized or reduced clay falls into asuitable receptacle, and from which it is taken by elevator-buckets tothe pressing-machines, or disposed of in any other suitable manner.

Instead of providing the disk F with the peripheral arms or beaters G, Imay use a screen surface similar to but of a larger mesh .than thescreen surface of the disk H, and such I consider as within the spiritof my invention.

It will be noticed that the clay is projected through the openings L inthe chamber K by centrifugal force, and the weight of the clay in thehopper N into the space between the disks F H, and that the volume ofclay is caused to rotate with the disk Hand be forced by centrifugalaction toward the periphery of the disk, where it is met by the heatersin the periphery of the disk F, revolving in the opposite direction,which changes the motion of the body of clay and causes the outer edgeof the same to travel in a direction contrary to that of the inner bodyof the clay, so that a continual collision will take place of one bodyof the clay upon the other until it is reduced 0 to the finest possiblecondition, the cohesion of the particles being completely destroyed.

In this finely divided and powdered condition-a,

the clay is driven by centrifugal force through the screen-plates and isdirected downward by 5 the'outer case or shell, S, through the openingR.-

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

1. A clay reducing and disintegrating machine of the characterdescribed, consisting of the rotating disk H, having a perfora edcentral feed chamber and peripheral screen, and the disk F, adapted totravel in a reverse direction to that of the disk H, as described,whereby the outer portion of the clay is caused to travel in a reversedirection to the inner body of the clay, and the clay reduced to afinely-divided condition by attrition or collision of the particles, asset forth.

2. In a clay-reducer, the disk H, provided with the perforated centralhub, K, and the peripheral screen 0, adapted to travel in one direction,in combination with the disk F, adapted to travel in a direction thereverse of the disk H, the disk F being provided with a series of arms,G, arranged close together in the outer edge of said disk, as set forth.

I). In a clay-reducer, the disk II, provided with the central perforatedchamber, K, and the feedspout adapted to project into said chamber,whereby the clay is fed into the central portion of the disks andprojected toward the periphery of the disk by centrifugal force, as setforth.

4. In a clay reducer or pnlverizer, the disk H, provided with theperforated chamber K and a screen surface secured to its periphery,which projects over the disk F, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

J. C. ANDERSON.
